Shell下配置虚拟接口vintf0的ip地址，即为交换机ip地址。
ifconfig vintf0 192.168.21.231
2.端口状态
2.1 获取端口当前工作状态
BCM.0> ps ge12

ps ge8
ena/ speed/ link auto STP lrn inter max loop
port link duplex scan neg? state pause discrd ops face frame back
ge8 up 1G FD SW Yes Forward TX RX None FA SGMII 16356
如上所示命令调用下面两个驱动接口获取端口状态
Void port_info_init(int unit, int port, bcm_port_info_t *info, uint32 actions)
int bcm_port_selective_get(int unit, bcm_port_t port, bcm_port_info_t *info)
Actions = BCM_PORT_ATTR_ALL_MASK
2.2 获取端口的转发状态
BCM.0> debug bcm api
debug bcm api
BCM.0> stg show 1
stg show 1
API: bcm_stg_vlan_list(0,1,...) -> 0 Ok
STG 1: contains 2 VLANs (1-2)
API: bcm_stg_vlan_list_destroy(0,...) -> 0 Ok
BCM.0> stg stp 1
stg stp 1
STG 1:
API: bcm_port_config_get(0,...) -> 0 Ok
API: bcm_stg_stp_get(0,1,1,...) -> 0 Ok
API: bcm_stg_stp_get(0,1,2,...) -> 0 Ok
...
API: bcm_stg_stp_get(0,1,55,...) -> 0 Ok
Forward: ge,xe,hg
如上所示，调用驱动接口获取端口stp 状态。
bcm_stg_stp_get(int unit, bcm_stg_t stg, bcm_port_t port, int *stp_state)
2.3 设置端口的转发状态

命令在调用驱动接口
bcm_stg_stp_set( int unit, bcm_stg_t stg, bcm_port_t port, int stp_state)
设置端口ge15 stp 状态为Block之后，查看端口状态，显示为block，打入广播报文，其他端口没有广播报文统计计数。

修改L2_user_entry 表index 为3的表项，mac 为0x000000000003，从block 的ge12打入构造的目的mac为0x03的二层报文，其他端口有统计计数。
或者通过如下方式增加L2_user_entry表项

优先级映射实现从QoS优先级到内部优先级或从内部优先级到QoS优先级的映射，并利用DiffServ域来管理和记录QoS优先级和服务等级之间的映射关系。
对于进入设备的报文，将报文携带的优先级或者端口优先级映射为内部优先级，然后根据内部优先级与队列之间的映射关系确定报文进入的队列，从而针对队列进行流量整形、拥塞避免、队列调度等处理，并可以根据配置修改报文发送出去时所携带的优先级，以便其他设备根据报文的优先级提供相应的QoS服务。
对报文进行优先级标记，可以打在二层报文上，也可以在三层(ip)报文头上。

10. 问题及解决方法
以大于200p/s发送二层广播报文时出现发送流控问题，此时cpu口在vlan 1内，将cpu口从vlan中移除，不会发送流控，对于需要上送cpu的报文可以通过添加L2 Entry表项或设置寄存器或ACL规则上送，此外需要配置cpu上送报文限速。

通过添加L2 Entry，目的mac为cpu mac的ICMP报文实现上送
BCM.0>L2 add mac=02:10:18:db:88:47 vlan=1 pbm=cpu0 Static=true ReplacePriority=false Replace=false L3=true
2. 寄存器配置ARP报文上送
BCM.0> sc ArpReplyToCpu=1
BCM.0> sc ArpRequestToCpu=1
3. 通过FP规则配置EtherType 为0x0806的ARP报文上送cpu
配置如下：
BCM.0> fp init
BCM.0> fp qset add EtherType
BCM_FIELD_QSET_ADD(EtherType) okay
BCM.0> fp group create 0 0
BCM.0> fp entry create 0 1
BCM.0> fp qual 1 EtherType 0x0806 0xfff
BCM.0> fp action add 1 CopyToCPU 0 0
BCM.0> fp entry install 1

函数sh_init 中，对从rc.soc中读取到的，或通过命令下发的init soc, init bcm , init mmu, init all 进行处理，下发init bcm时，调用bcm_init 函数。
在_bcm_modules_init中，完成各个模块的初始化。
首先，初始化tx, rx ，然后注册驱动功能处理函数指针，实现根据芯片类型dispatch到对应的处理。
如下为_bcm_modules_init 中处理流程：
而由bcm_init 调用到bcm_esw_init 是通过dispatch 实现的。
Src/bcm/Control.c 中的bcm_init 调用函数指针_dispatch_init[BCM_DTYPE(unit)](unit); 分发到具体的芯片处理初始化函数。
在src/bcm/Control.c中，定义宏BCM_DLIST_ENTRY 参数为_dtype 时，声明的外部函数为
Int bcm_##_dtype##_init(int);
#define BCM_DLIST_ENTRY(_dtype)\
extern int bcm_##_dtype##_init(int);
#include <bcm_int/bcm_dlist.h>
#define BCM_DLIST_ENTRY(_dtype)\
bcm_##_dtype##_init,
static int (*_dispatch_init[])(int) = {
#include <bcm_int/bcm_dlist.h>
};
在bcm_dlist.h 中，定义
#ifdef BCM_ESW_SUPPORT
BCM_DLIST_ENTRY(esw)
#endif
这样，支持esw类型的芯片（Helix4）调用_dispatch_init 时，就分发到bcm_esw_init 函数处理。
和芯片初始化相关的函数定义在Src/bcm/Control.c中，和功能相关的函数定义在src/bcm/Dispatch.c中。
上面为一次分发调用过程，此外还有多次分发调用过程。
例如src/bcm/Dispatch.c 中的bcm_l3_init，首先分发到src/bcm/esw/L3.c 中的bcm_esw_l3_init，在其中再调用
mbcm_driver[unit]->mbcm_l3_tables_init(unit),
mbcm_l3_tables_init 是一个函数指针，在src/bcm/esw/Mbcm.c 的mbcm_init 中，通过
mbcm_driver[unit] = &mbcm_firebolt_driver;
将函数指针数组mbcm_firebolt_driver 赋值给mbcm_driver，这样，调用mbcm_l3_tables_init就会调用到函数指针数组中对应的bcm_xgs3_l3_tables_init 。
